a) I don't have a compiler for any other language installed, so I have no idea what would happen.
b) It doesn't matter what would happen. This is LabVIEW, not VB. It's behaviour is cross-platform and has been determined by NI, not Microsoft. Within these bounds it is very logical and consistent. The changing value of a boolean has been around long before LV had the event structure. A boolean button doesn't need you controlling it in order to change its value and you don't have to use events. Events like value change and mouse up are there to give you more power and they usually work very well. If you have any specific question, I suggest you ask it in plain words.
